Abstract
A linear motor supporting apparatus for a linear motor elevator capable of greatly dampening a load from a stator when a relative displacement of the stator and guide rails occur, includes a linear motor including a rotor and a stator; a tensile force adjusting device, disposed below the stator, for adjusting a tensile force upon the stator; and a stator displacement adjusting device, disposed between the tensile force adjusting device and a supporting frame, for greatly reducing a load upon the stator by moving the stator by as much as a relative displacement between the stator and the rotor.
Claims5
A linear motor supporting apparatus for a linear motor elevator, comprising:
- a linear motor including a rotor and a stator;
- tensile force adjusting means, disposed below tile stator, for adjusting a tensile force upon the stator;
- and
- stator displacement adjusting means, disposed between the tensile force adjusting means and a supporting frame of the elevator, for reducing a load upon the stator by permitting movement of the stator to compensate for any lack of coincidence in the vertical direction between the stator and the rotor.
